                           DATE TO MONDAY, MAY 2, 2005


Dear Stockholder:

         The following information (the "Supplement"), which is being mailed to
stockholders on or about April 20, 2005, supplements and amends the Notice of
the Special Meeting of Stockholders (the "Special Meeting") of Ramp Corporation,
a Delaware corporation (the "Company") and the accompanying Proxy Statement (the
"Proxy Statement"), each dated March 16, 2005, furnished in connection with
solicitation of proxies on behalf of the Board of Directors of the Company for
use at the Special Meeting which was originally held on Monday, April 11, 2005
at 10:00 a.m. local time at the principal offices of the Company, 33 Maiden
Lane, 5th Floor, New York, New York 10038, and adjourned solely for purposes of
Proposal 2 and Proposal 3, to Monday, May 2, 2005 at 10:00 a.m. local time at
the principal offices of the Company. This Supplement, which should be read in
conjunction with the Proxy Statement, is first being furnished to stockholders
of the Company on or about April 22, 2005.


                           PURPOSE OF THIS SUPPLEMENT

         On March 31, 2005, the Company entered into a securities purchase
agreement with Alpha Capital AG, Ellis International Ltd. and Double U Master
Fund LP, each an institutional investor, pursuant to which the Company agreed to
sell, and the investors agreed to purchase, 8% convertible redeemable debentures
in the aggregate amount of $2,600,000 and five-year warrants to purchase an
aggregate amount of 2,080,000 shares of common stock at an exercise price of
$1.25. The debentures are convertible into common stock of the Company at an
initial conversion price of $1.25. A first tranche of $1,050,000 closed on March
31, 2005, and a second tranche of $250,000 closed on April 11, 2005 for an
aggregate amount of $1,300,000 at the first closing. A second closing of
$1,300,000 shall occur upon the completion of certain closing conditions set
forth in the securities purchase agreement. The Company is obligated to redeem
one-fifth of the principal and interest amount on the debentures in cash or, at
the option of the Company, shares of common stock, on the first day of each
month, commencing on the earlier of (a) July 29, 2005, and (b) the first date
following the 20th day after the effective date of the registration statement
registering for resale the securities issuable upon conversion of the
debentures, and ending upon the full redemption of the debentures. If the
Company elects to make redemption payments in shares of common stock, the
principal amount is convertible based upon a conversion price equal to the
lesser of the initial conversion price or 85% of the average of the three lowest
closing bid prices for the Company's common stock during the 20 trading days
immediately prior to the monthly redemption date. The Company is also obligated
to pay 8% in interest on the outstanding principal on the debentures (i) on the
effective date on which the debentures are converted into shares of common stock
of the Company, (ii) on each monthly redemption date or (iii) on the maturity
date, at the interest conversion rate.

         Assuming the maximum amount of $2,600,000 is purchased, the Company
agreed to issue to the investors additional investment rights to purchase
additional debentures in the aggregate principal amount of up to $866,580 along
with five year warrants to purchase an aggregate of 693,264 shares of our common
stock, on the same terms and conditions as the original debentures and warrants.
The debentures


                                       2


and warrants are subject to customary protection against dilution.  At the first
closing,  the Company paid a cash fee of 3% of the original  purchase  price for
liquidated  damages owed to the investors in the January 2005 Private Placement.
In addition,  upon each closing, our financial advisors, J.H. Darbie & Co., Inc.
and  Harborview  Capital  Management  LLC,  are entitled to receive a warrant to
purchase  seven  percent  (7%) of the  shares  of  common  stock  issuable  upon
conversion of the debentures at an exercise price of $1.25.

         In connection with the above transactions and in order to obtain the
waiver and consent of the investors in the January 2005 Private Placement, the
Company entered into an amendment (the "Amendment"), dated as of March 31, 2005,
to the securities purchase agreement, dated as of January 12, 2005, with DKR
Soundshore Oasis Holding Fund Ltd., Harborview Master Fund, L.P. and Platinum
Partners Value Arbitrage Fund, L.P., each an institutional investor, pursuant to
which the initial conversion price for the 8% convertible redeemable debentures
in the aggregate amount of up to $4,000,000 ($2,000,000 of which were sold to
the investors at the first closing) was reduced from $2.40 to $1.25 and the
exercise price of the five-year warrants to purchase up to 1,666,667 shares of
common stock was reduced from $2.40 to $1.25. In addition, the additional
investment rights to purchase additional debentures in the aggregate principal
amount of up to $1,333,200 along with five year warrants to purchase an
aggregate of 550,000 shares of the Company's common stock, on the same terms and
conditions as the original debentures and warrants, were modified by the
Amendment to reduce the conversion and exercise price from $2.40 to $1.25.
Moreover, the conversion price of convertible redeemable debentures issued by
the Company in the aggregate principal amount of $546,015 and the exercise price
of warrants to purchase an aggregate of 227,506 shares of common stock issued by
the Company was reduced from $2.40 to $1.25. Pursuant to the Amendment, as
further amended by agreement on April 12, 2005, if the Company does not file a
registration statement covering the shares of common stock underlying the
securities issued in the January 2005 Private Placement on or before April 13,
2005, the original investors in the January 2005 Private Placement have the
right not to purchase convertible debentures and warrants otherwise required at
the second closing. The Company complied with this requirement by filing a
registration statement with the SEC on April 13, 2003.

         Proposal 2 to the Proxy Statement is hereby amended by this Supplement
as follows:

         As a result of the March 2005 Private Placement transaction set forth
above, the amount of $546,014, equal to one hundred and twenty percent (120%) of
the outstanding principal and interest amount of the Notes, was automatically
converted into 8% convertible redeemable notes, which notes have a conversion
price of $1.25 per share, initially convertible into 227,506 shares of common
stock, and common stock purchase warrants to purchase an aggregate of 227,506
shares of Common Stock at an exercise price of $1.25 per share.

         Proposal 3 to the Proxy Statement is hereby amended by this Supplement
as follows:

         On January 12, 2005, the Company entered into a securities purchase
agreement ("Securities Purchase Agreement") with DKR Soundshore Oasis Holding
Fund Ltd., Harborview Master Fund, L.P. and Platinum Partners Value Arbitrage
Fund, L.P., each an institutional investor, pursuant to which the Company agreed
to sell, and the investors agreed to purchase, 8% convertible redeemable
debentures ("Convertible Debentures") in the aggregate principal amount of up to
$4,000,000 and five-year warrants ("January Warrants") to purchase up to
1,666,667 shares of common stock at an exercise price of $1.25 (the "January
2005 Private Placement"). The Convertible Debentures are convertible into Common
Stock at a conversion price of $1.25. A first closing of $2,000,000 occurred on
January 13, 2005 ("First Closing") and a second closing of $2,000,000 shall
occur upon the completion of closing conditions set forth in the Securities
Purchase Agreement ("Second Closing").
